(HTTP Status Code: 403)

Hello my good friends!On Thursday I bought the game Batman Arkham City GOTY and it came with a code to download Batman: Year One, which can only be downloaded with an account in USA. Well, I enter the code, everything right, the download screen but I get a message that says "There was a server error. (HTTP Status Code: 403)". What can I do? Appears in my download list, so I can try to download it as many times as I want, but doesn't download anything. I don't if the code still works.
